usually在後doesn't在前do和does屬於助動詞 don't doesn't是它們的否定形式的縮略形式，屬於一般現在時態的否定句型，正確的句子格式應該是主語＋助動詞don't或 doesn't 再＋usually +動詞原形。常用的時間狀語還有often sometimes always等。希望有用哦！

usually只能用作狀語,位於實義動詞之前,系動詞、助動詞或情態動詞之後,也可放在句首或句末表示強調。用於否定句時,多位於實義動詞與系動詞、助動詞或情態動詞的中間

usually是頻度副詞,意思是“常常”“習慣於”,有遵循常規的意思,其經常性約為90%

例句：

We usually go by car.我們通常開汽車去。

How long does the journey usually take?這段旅程通常需要多長時間？

She felt more than usually hungry after her excursion...遠足後，她比平時感覺更餓。

What time do you usually wake up in the morning?通常你早晨幾點鐘醒？

Business is usually quieter at this time of year.

每年這個時節，生意往往比較清淡。

usually放在助動詞的後面，例如，A patient will usually listen to the doctor's advice.（病人通常都將聽醫生的建議）。
